Cook the rice: Make your rice according to package directions.
White rice is fluffier and quicker, while brown rice adds a nutty bite and extra fiber. Keep it warm.
Season the chicken: In a bowl, toss the chicken pieces with olive oil, garlic powder, onion powder, smoked paprika, salt, and pepper until evenly coated.
Sear the chicken: Heat a large skillet over medium-high. Add the seasoned chicken in a single layer.
Cook 4–6 minutes, stirring once or twice, until browned and cooked through.
Buffalo it up: Reduce heat to medium. Pour in the Buffalo sauce and add the butter if using. Stir to coat and simmer 1–2 minutes until glossy and slightly thickened.
Prep the toppings: While the chicken cooks, chop lettuce, dice celery and carrots, slice green onions, and cube the avocado.
Rinse beans and corn if using.
Assemble the bowls: Spoon a bed of rice into each bowl. Top with Buffalo chicken. Add lettuce, celery, carrots, corn, beans, avocado, and green onions.
Finish with flavor: Sprinkle blue cheese or cheddar.
Drizzle with ranch or blue cheese dressing. Add herbs and a squeeze of lime. Serve right away.
